Question

3) In the natural numbers from 10 to 250, how many are divisible by 4?

​

Answer 1

Answer:

Natural numbers from 10 to 250 divisible by 100 are: 12, 16, ...., 248

Here, a = 12 and d = 4

» tn = a + (n - 1) d

» 248 = 12 + 4 (n - 1)

» n - 1 = 236/4

» n = 59 + 1 = 60

Therefore, 60 natural numbers are divisible by 4.
